Is (2,2) a solution of the system

pashok25 [27]

Answer:

Hi, you don't provide us with the system here...

to figure out if 2,2 is a solution of the system, you have to plug the value of 2 in for both x and y in the system, and solve to see if it comes out or not...

If you provide the system I can definitely help you out more specifically!

Enter a recursive rule for the geometric sequence. 6, −18, 54, −162, ...

svlad2 [7]

Answer:

The required recursive formula is:

$a_n=(-3)\times a_{n-1}$

Step-by-step explanation:

We are given a geometric sequence as:

6,-18,54,-162,.....

Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.

Let $a_n$ represents the nth term of the sequence.
